DEMI Next vs. DEMI Grow Comparison:

Nuna has delivered several key improvements for the DEMI Next when comparing it to the first-generation DEMI Grow stroller.

DEMI Next comes with new Rider Board included
The clever new Rider Board creates additional flexibility and travel options for growing families. Included with the purchase of the new DEMI Next Stroller, the Rider Board easily attaches to the stroller and provides a safe riding platform for little passengers up to 50 lbs. With two swivel wheels for easy maneuvering, the Rider Board easily folds with the stroller and can be flipped into the stroller when not in use.

Larger Storage Basket
Making the most of your family journeys can often mean having enough room for all your essential goodies. The DEMI Next more than doubles the underseat basket capacity from 10 lbs. to 22 lbs., providing some serious, next-level space for all your essentials while on the go.

Redesigned Canopy
The updated Aire protect canopy™ now boasts ventilation panels and a full privacy cover all in one product. The built-in, airy mesh privacy drape and ventilation panels in the canopy provide for optimal airflow and sustained comfort.

New 4-Position Recline
Easily adjust the recline with one hand to one of four recline positions available with the DEMI Next. Provide maximum comfort for the little one with an upright backrest angle for comfortable, just-right rides.

New Footrest Design
One-hand adjustable calf support and the new footrest design provides optimal comfort and accommodates growing little ones.

Larger Front Wheels
The front wheel size has been increased by 1 inch to 8.5 inches on the DEMI Next to provide for optimal maneuverability and flexibility. The wide, swivel-lock front wheels are tough, foam-filled and ready for any terrain.

Usage From Birth
Furthering the DEMI Grow usage recommendation, the DEMI Next can be utilized from birth to 50 lbs.

DEMI Next Stroller Modular Options:

With the addition of the included Rider Board, the DEMI Next is arguably the most versatile stroller on the market. With an incredibly flexible and adaptable design, the new DEMI Next can be configured into an amazing 25 possible modular combinations in both single and double modes. The Nuna DEMI Next is also compatible with all Pipa series infant car seats and works seamlessly with the additional DEMI Next Sibling Seat and Bassinet (sold separately).

Stroller for One Child: Enjoy different strolling modes with the little one depending on the desired activity or mood of your passenger. Utilize the Stroller Seat or your Nuna Pipa series infant car seat in either parent-facing or forward-facing mode, or simply pop on the handy and super comfortable Bassinet, to let baby enjoy a snooze on the go.

Double Stroller for a Toddler and a Newborn: Expecting a new bundle of joy? The DEMI Next is easily transformed from a single to a double stroller to make way for the new little one. Simply add a Sibling Seat and you are ready for adventures with double the fun. You have the flexibility to position the newborn in the upper seat closer to you to provide added attention, while your toddler can stroll comfortably in the lower seat while they gain independence.

Double Stroller for Twin Babies: Preparing for twin bundles of joy? The DEMI Next has you double-covered. Stroll your twins in style with either two Pipa infant car seats or two Bassinets, and accommodate both your little passengers comfortably and safely as they grow and their shifting needs change

Tag-a-long with the Rider Board: Create additional flexibility and travel options for your growing family and provide a cool ride for a toddler up to 50 lbs. The Rider Board easily attaches to the back of the stroller and gives a safe platform for your older tag-a-long passenger.

Buy it! Lifesaver!
Size: 16oz
Yes, buy it when you don't have a spare tire because you will need it! I live in Florida and flat tires are just part of living here! Saved my life twice already and is absolutely self explaining! Cheaper then a spare tire, lighter than one too! Just throw it in your trunk and best case you will never need it but just in case!

Difficult to use and eventually hose end broke
Size: 24oz, Size: 24oz
I purchased this can of Fix-A-Flat to fix, what I believe, is a rim leak on my truck tire which needs to be filled once every week or so. When I attempted to use the product I let some air out of the tire (down to 25 psi) so it would be easier to dispense the contents. The instructions on the can say to have the valve on the tire at the 6 o'clock...which I did as well. When I attempted to make the connection using the swivel connector on the can's hose it was difficult. The hose on the can is very short and stiff and because it came coiled in the can's lid, did not want to straighten out making connecting it to the tire a very awkward process. It was hard to screw the hose end on the valve without it binding so it felt like it was cross-threading. I have machined aluminum valve caps and they go one very easily so I know the threads on the tire's valve stem are clean. I finally did get it on and when I attempted to dispense the contents it filled the hose but that was about it. I could not see any contents flowing thru the hose at all. I assumed it was not on far enough so I took it off to try again and the contents sprayed everywhere showing it was indeed under pressure....just not going into the tire. After multiple tries the hose end eventually just broke off and stayed on the tire's valve stem. I was able to get it off, but at this point the can is useless to me. Obviously I cannot and will not recommend this product. I have used this product before and had success, but that was when the hose was longer and wired to the side of the can making it much easier to use, versus how they are shipped now. I would recommend going with another product or possible going to a box store (which is what I plan to do) to find one that does not have this design. At the very least, if you do choose to disregard this review, I would try it with the tire's valve stem at the 3 or 9 o'clock position which might make it easier to thread the hose end on to the valve stem,. Also, if you choose to go this route you might just be throwing your money away. I attempted to get a refund from Amazon and was directed to the manufacture's web site. From there you are directed to use the 800 number of leave a general message that is in no way connected to your Amazon purchase. Past experience tells me it will not be an easy process so it looks like I am out the $12.

This is a necessity for anyone that tries a car!!
Size: 20oz 6pk
I haven’t used this yet, but I bought a case to give to my family members. My friend who came outside to a flat tire. It was a Sunday in Utah so there was really no one that could fix it. Walmart told her to get this product. She had to drive home immediately following using this product (300 miles) It has been over two months now and my niece is still driving on that tire. It was a brand new tire that was costly so she decided to just wait and see how long this product will work. Great gift for anyone in the family that drives. This does not work on a blown tire. If you wake up in the morning and your tire is flat, or you get out of class and your tire is flat, just use this product and no calls need to be made.

Essential Emergency Kit That Every Vehicle Should Have
After experiencing a flat tire on a remote highway late at night, I realized how unprepared I was for roadside emergencies. That experience led me to purchase the AUTOWN Flat Tire Repair Kit, and I'm incredibly grateful to now have this comprehensive solution in my vehicle. This kit has already saved me twice from having to call for expensive roadside assistance, and the peace of mind it provides is absolutely priceless. The 31-piece kit is impressively complete. It includes everything you need to handle a flat tire emergency, from the tire plugs themselves to insertion tools, rasps, and even extras that many cheaper kits omit. The variety of plug sizes means you can handle different types of punctures, and having multiple plugs means you're prepared for more than one emergency before needing to restock. What sets this kit apart is the quality of the tools. The T-handle insertion tool feels solid and well-made, not like the flimsy plastic tools that come with some budget kits. The reamer tool cuts through damaged rubber cleanly and efficiently, making it easy to prepare the puncture hole for the plug. Having used cheaper tire repair kits in the past that broke during use, I really appreciate the durability and reliability of these tools. The storage case is another thoughtful feature that makes this kit practical for vehicle storage. Everything fits neatly in the organized case with dedicated spaces for each component, which means you can quickly find what you need during an emergency. The case is compact enough to fit in a glove box or under a seat, but it's also rugged enough to withstand being rattled around in a trunk without falling apart. Using this kit is surprisingly straightforward, even for someone without extensive automotive experience. The process involves identifying the puncture, using the reamer to prepare the hole, inserting the plug with the T-handle tool, and trimming the excess. I was able to successfully repair a puncture on my first attempt following the basic instructions, and the repair has held perfectly for months of daily driving.
